Answer: 9%
Step-by-step explanation:
Plug the values into the second equation to see if they end up equaling 0.
-4: 2(-4)^2 - 6(-4) - 8 = 0
2(16) + 24 - 8 = 0
32 + 16 = 0
Not -4
-1: 2(-1)^2 - 6(-1) - 8 = 0
2 + 6 - 8 = 0
8 - 8 = 0
0 = 0
Yes -1
0: 2(0)^2 - 6(0) - 8 = 0
0 - 0 - 8 = 0
Not 0
1: 2(1)^2 - 6(1) - 8 = 0
2 - 6 - 8 = 0
-12 = 0
Not 1
4: 2(4)^2 - 6(4) - 8 = 0
2(16) - 24 - 8 = 0
32 - 32 = 0
0 = 0
Yes 4

Or use the quadratic equation ( - b +/- sqrt( b^2 - 4ac)) / 2a
————
a would be 2–
b would be -6–
& c is -8

Answer:
- repeating
- repeating
- repeating
- non-repeating
Step-by-step explanation:
There are two ways that repeating decimals are indicated. One of them is putting an overbar over the digits that repeat. The other is to show the repeat of digits, followed by an ellipsis (...).
Since they are congruent rectangles, they have the same side lengths.
The area of a rectangle is width times height
11(18)=198 square inches.
